you have very bad skin problem.It is not possible that you dont want to remove your cloths and ask doctor for treament.
simple rule,
there is no 'free visa' in Qtr.you have to work to your sponsor only.
first tos is after two years if you have stamped rp
second tos(transfer of sponsrship)can be done after next year only
you can not transfer from personal to commercial visa
once you cancelled rp comeback after 2 years in normal case
and there are lot of obligations but you have to follow ql,there are very healthy informative notes
---and good luck
